The Perpetrator in the Prep Closet The Crime: For the past two months, Mrs. Oshinski and Mr. Rumpf, 7th grade science teachers at Highland Middle School, have been combining their science knowledge to create a new formula for a health shake. They believe it will revolutionize the fitness industry by incorporating protein for strength building and ingredients like Vitamin C for immunity. Using Mr. Rumpf s knowledge of food research that he gained while working at Gatorade, with Mrs. Oshinski s experience as a personal trainer, they believe this new shake will bring in millions. Mrs. Oshinski offered free training sessions to teachers at Highland, and as part of the program, each teacher was given a one month supply of the health shake. On Friday night, Mrs. Oshinski stayed late to finish grading papers and then do some further work on the recipe. Mr. Rumpf was also still at Highland, holding volleyball practice. Around 5:30 PM, an intruder, disguised in a black mask, snuck into the prep closet. Mr. Rumpf was suffering from digestive problems and ran back to his room to get medicine. The surprised intruder attacked Mr. Rumpf, causing him to hit head on the lab table. Mr. Rumpf fought back against the intruder and tried to grab the mask off of his/her head. Mrs. Oshinski, heading back toward the prep closet to clean up, heard the scuffle, and rushed in, hitting the intruder with a kettle bell. The intruder managed to get past them both, and ran out the prep door and out the nearby exit. There was a note left behind with a phone number written on it. After stopping the bleeding on Mr. Rumpf s head, they rushed to the office to contact administration, who then called the Libertyville police. The police immediately began searching the premises and gathered the following evidence. The Evidence: Evidence gathered at the scene includes: 1. Fingerprints found at the scene 2. Blood spatter from the prep room into the hallway 3. 15 different material residues found at the crime scene. 4. Hair and fibers found at the crime scene. 5. The chromatography from the paper with the phone number. 6. Physical evidence found at the crime scene.
After questioning several witnesses, the police narrowed down their investigation to the five key suspects. The Suspects: 1. Mr. Cholipski - The dean at Highland, Mr. Cholipski is a sports enthusiast. He was part of the twice a week training group, and the protein drink trial group.

Mr. Cholipski has been remodeling his new home with drywall and has a pet dog named Fred. He often wears dress clothes and a tie. 2. Mr. Liu - The 8th grade chemistry and physics eacher, Mr. Liu, wanted to be part of the research team because he knew that Mrs. Oshinski and Mr. Rumpf were on the right track.

He is 5 8 tall, has dark brown hair, and dark brown eyes. Mr. Liu is known to frequent fast food restaurants and orders a gyro with potato chips. He often wears jeans and dress shirt. 3.
